First Aid Measures
【Ingestion】Never give anything by mouth to an unconscious person. Get medical aid immediately. Do NOT induce vomiting. If conscious ａnd alert, rinse mouth ａnd drink 2-4 cupfuls of milk or water.
【Inhalation】Get medical aid immediately. Remove from exposure to fresh air immediately. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. DO NOT use mouth-to-mouth respiration.
【Skin】Get medical aid immediately. Immediately flush skin with plenty of soap ａnd water for at least 15 minutes while removing contaminated clothing ａnd shoes. Wash clothing before reuse. Destroy contaminated shoes.
【Eyes】Get medical aid immediately. Do NOT allow victim to rub or keep eyes closed. Extensive irrigation is required (at least 30 minutes).

Handling ａnd Storage
【Storage】Keep away from heat, sparks, ａnd flame. Keep away from sources of ignition. Keep container closed when not in use. Store in a tightly closed container. Store in a cool, dry, well-ventilated area away from incompatible substances. Corrosives area. Do not expose to air. Store protected from moisture. Store under an inert atmosphere.
【Handling】Use only in a well ventilated area. Empty containers retain product residue, (liquid and/or vapor), ａnd can be dangerous. Keep container tightly closed. Avoid contact with heat, sparks ａnd flame. Do not get on skin or in eyes. Do not ingest or inhale. Handle under an inert atmosphere. Store protected from air. Do not allow contact with water. Discard contaminated shoes. Do not pressurize, cut, weld, braze, solder, drill, grind, or expose empty containers to heat, sparks or flames. Keep from contact with moist air ａnd steam.

【Fire Fighting】Wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), ａnd full protective gear. During a fire, irritating ａnd highly toxic gases may be generated by thermal decomposition or combustion. Use water spray to keep fire-exposed containers cool. Combustible Liquid. To extinguish fire, use water, dry chemical, chemical foam, or alcohol-resistant foam. Use water spray to cool fire-exposed containers. Do NOT get water inside containers.
【Fire Potential】This chemical is combustible.

Accidental Release Measures
【Small spills/leaks】Absorb spill with inert material, (e.g., dry sand or earth), then place into a chemical waste container. Clean up spills immediately, using the appropriate protective equipment. Remove all sources of ignition. Provide ventilation. Place under an inert atmosphere. Do not get water inside containers.
